摘要:

重夸克在高能重离子碰撞产生的夸克-胶子等离子体(QGP)中的扩散,长期以来被认为是探测其输运性质的极佳探针。此外,实验观测到的重味强子携带着关于被输运夸克强子化过程的宝贵信息。在此,我们回顾了QGP中重夸克相互作用理论发展的最新进展,以及它们与非微扰强子化过程的关联,并讨论了在RHIC和LHC的重离子碰撞中相关唯象学的最新现状。QGP中重夸克的相互作用也构成了描述重夸克偶素的核心基础,并控制着它们的输运参数。因此,我们将重点关注旨在统一描述介质中开重味和隐重味粒子的理论方法,并讨论如何通过格点QCD“数据”对其进行约束,以及如何利用它们来推导微观相互作用的基本性质和强耦合QGP的涌现谱性质。

英文摘要:

The diffusion of heavy quarks through the quark-gluon plasma (QGP) as produced in high-energy heavy-ion collisions has long been recognized as an excellent probe of its transport properties. In addition, the experimentally observed heavy-flavor hadrons carry valuable information about the hadronization process of the transported quarks. Here we review recent progress in the theoretical developments of heavy-quark interactions in the QGP and how they relate to the nonperturbative hadronization process, and discuss the recent status of the pertinent phenomenology in heavy-ion collisions at the RHIC and the LHC. The interactions of heavy quarks in the QGP also constitute a central building block in the description of the heavy quarkonia which controls their transport parameters as well. We will thus focus on theoretical approaches that aim for a unified description of open and hidden heavy-flavor particles in medium, and discuss how they can be constrained by lattice QCD "data" and utilized to deduce fundamental properties of the microscopic interactions and emerging spectral properties of the strongly coupled QGP.
